钣金加工生产中链接方法(常用)

钣金加工生产:随着生产设备的不断更新与发展,绝大多数的成形工艺是在机器上完成的,手工方法往往作为补充加工活修整工作,但在单件生产情况下,或一些形状比较复杂的零件,仍离不开手工操作及加工。钣金加工件手工成形主要是利用一些简单的胎型、靠模和各种各样的工夹具来完成,手工成型主要采取以下方法:弯曲、放边、收边、拔缘、拱曲、卷边、焊接缝的校正等等。

钣金加工生产:不过我们今天所与大家分享的是钣金加工件的联接方法:钣金联接主工采用焊接、螺纹联接、铆接合粘接,我公司采用的联接方式:焊接、螺纹联接合铆接。

焊接——是对焊件进行局部或整体加热或使焊件产生塑性变形,或加热与塑性变形同时进行,实现永久连接的工艺方法,可分为:手工电弧焊、气体保护电弧焊、激光焊、段焊和接触焊,我司主工采用气体保护焊接接触焊。

气体保护电弧焊——在进行气体保护电弧焊时,电极电弧区及焊接熔池处在保护气体的保护下,采用氩气保护焊缝表面梅雨氧化物及夹杂物。可以在任何空间位置施焊,可以用肉眼观察焊接的成形过程并进行调整生产效率高。

接触焊 接触焊时瞬时加热连接部位子熔化状态或非熔化状态下对被焊件加压形成焊接接头的焊接方法,它可分为对焊、点焊和缝焊。

螺纹联接 螺纹联接局域安装 容易、拆卸方便、操作简单等优点,常用于可拆的钢结构连接,它可分为螺钉联接合螺栓联接。

铆接 铆接是用铆钉将金属结构的零件或组合件连接子,一起的方法,铆钉种类较多,我们常用的铆钉有封闭形圆头抽芯铆钉、封闭形沉头抽芯铆钉及开口型圆头抽芯铆钉、开口型沉头抽芯铆钉。

粘接 用粘接剂将所需连接就按粘接子,一起的一种连接方法。

Link method in sheet metal processing (commonly used)

Sheet metal processing production: with the continuous updating and development of production equipment, the vast majority of the forming processes are completed on the machine. Manual methods are often used as supplementary processing and dressing, but in the case of single piece production, or some parts with more complex shapes still can not be separated from manual operation and processing. Manual forming of sheet metal parts is mainly done by using some simple type of tire, mould and various kinds of jig. The following methods are mainly adopted in hand forming: bending, edge setting, edge collecting, drawing edge, arch, winding, welding seam correction and so on.

Sheet metal processing production: but what we share with you today is the joint method of sheet metal processing parts: welding, threaded connection, riveting joint bonding, joint methods adopted by our company: welding, threaded connection and riveting.

Welding is a process method for the welding parts to be heated locally or as a whole or to make plastic deformation of the welding parts, or to make a permanent connection between the heat and the plastic deformation. It can be divided into: manual arc welding, gas shielded arc welding, laser welding, segmental welding and contact welding. The main work of our company is gas protection welding contact welding.

Gas shielded arc welding - when the arc welding of gas is carried out, the electrode arc area and the welding pool are protected by the protective gas, and argon is used to protect the surface of the weld and the inclusions on the surface of the weld. It can be welded in any space position. It can observe the forming process of the welding with naked eyes and adjust the production efficiency.

The welding joint of the welded joint under the instantaneous heating connection part of contact welding is divided into welding, spot welding and seam welding.

Threaded connection is easy to install, easy to disassemble and easy to operate. It is commonly used in detachable steel structure connection, which can be divided into screw connection and bolt connection.

Riveting is a method of connecting parts or combinations of metal structures with rivets. There are many kinds of rivets. The rivets commonly used are closed round head rivets, closed sinking head riveting rivets, open type round head riveting rivets and open head riveting rivets.

An adhesive for bonding is used to connect the required connections to the bonding joint.
